Our Production Process

From raw material to finished product -- every step is performed in-house with precision equipment, ensuring consistent quality at every stage.

1

Shot Blasting / Peeling Machine

Removes surface oxidation and defects from the steel, ensuring a clean and smooth surface for further processing. This critical first step guarantees optimal adhesion for subsequent treatments.

Surface Prep Oxide Removal
Shot Blasting and Peeling Machine for steel surface preparation
Pointing Machine reducing bar diameter ends for cold drawing
2

Pointing Machine

Reduces the diameter at the ends of the bars to prepare them for the cold drawing process. Precise pointing ensures smooth entry into the drawing die, preventing material waste and die damage.

End Reduction Draw Prep
3

Annealing Furnace

Enhances the material structure of the steel, improving its ductility and strength, which is crucial for successful cold drawing. Controlled heat treatment cycles ensure uniform metallurgical properties throughout each bar.

Fully Automated Phosphating & Soaping Line

Applies a uniform lubricating film to the steel bars, significantly improving the cold drawing process and enhancing surface quality. Full automation ensures consistent coating thickness across every batch.

Polishing & Straightness

Our polishing machine achieves a superior surface finish (Ra 0.4-0.8) for a smooth, high-quality result, while the straightening machine ensures excellent straightness across the full bar length -- meeting the tightest flatness tolerances.

Precision Cutting Machine

Provides accurate length control and tight tolerances, ensuring that the steel bars are cut to the exact specifications required. Our CNC-controlled cutting system minimises kerf loss and delivers burr-free, square-end cuts.
